USAGE

# generate the module changes for the Perl you are currently building
./perl Porting/corelist-perldelta.pl
# generate a diff between the corelist sections of two perldelta* files:
perl Porting/corelist-perldelta.pl --mode=check 5.017001 5.017002 <perl5172delta.pod

ABOUT

corelist-perldelta.pl is a bit schizophrenic. The part to generate the new Perldelta text does not need Algorithm::Diff, but wants to be run with the freshly built Perl.
